how can i install: glib/gtk 1.2.10
I would suggest getting Darwinport. Google darwinport and download the .dmg file. Install this on your system. You will probably have to add the path /opt/local/bin to your profile, otherwise you won't see the port command. Once you have added the path, you will need to sync with the commands
I don't think that this works reliably any more because R is now a universal binary, and darwinports doesn't make universal binaries (we certainly have problems with rggobi). Simon will know more about this. Hadley
